This International Standard specifies a laboratory
method (clause 6) and in situ methods (clause 7) for
the determination of the sound insulation performance
of sound-protecting cabins. The sound insulation performance
is the reduction in sound pressure level or
sound power level afforded by the cabin. The methods
are applicable to cabins with a small leak ratio
(e s 2 %).
This International Standard is applicable to a complete
cabin only and not to the individual components from
which it is made.
NOTE 1 Sound insulations for cabin components such as
wall elements, doors, windows, silencers, etc. should be
measured according to other relevant standards.
Requirements for the test environment in the laboratory
are based on those given in IS0 3741.
